Strap for Aquis GMT 43.5 Whale Shark Limited Edition

The Oris Aquis 01 798 7754 4175-Set is fitted with a 22mm lug width, a construction standard specific to this generation of the Aquis family. This measurement ensures compatibility with straps and bracelets engineered for mid-to-large dive watch models, guaranteeing a robust and proportionate attachment to the 43.50mm ceramic case.

The choice depends on intended use. For alternation between formal and sports settings, we recommend alligator with vegetable tanning in dark brown or grey calf leather with satin finish. For frequent diving or intense marine environments, FKM (Viton) rubber in anthracite grey or NATO nylon straps offer resilience against chlorine, saltwater, and rapid drying.

The strap is replaced by removing the connecting pins located at the lug extremities, using a spring bar tool or dedicated device. Insert the new 22mm strap and secure the pins through the keeper slots, ensuring full insertion into the lug grooves before tightening. If you lack the proper tool, consult a professional watchmaker.

Yes, the 22mm lug width of the Oris Aquis 01 798 7754 4175-Set is a standard that permits compatibility with straps from any manufacturer, provided they are constructed for this specific measurement. Milano Straps offers a complete range of 22mm straps in leather, rubber, and textile, customisable online and dispatched promptly, all tested on equivalent Aquis models.

An alligator or calf strap with vegetable tanning, if maintained regularly (monthly cleaning, conditioning every three months), retains structural and aesthetic integrity for 18–24 months of daily use in non-marine settings. Frequent exposure to saltwater, chlorine, or extreme thermal variations significantly reduces this duration. For exclusively subaqueous use, we recommend rubber or NATO straps, which suffer no degradation from continuous moisture.
